Speed is the rate of motion.That also can have friction in it.From newtons three laws of motion
The instantaneous speed is the rate of motion at any given time.
That is the object's 'speed'.

Speed is the rate of motion.
the rate of motion is distance over time
The rate of motion is Speed. (V=distance divided by time).
If you are staying in the same position and not moving, then your rate of motion is zero.
The rate of change of motion is called jerk, jolt, surge, or lurch. The rate of change is derivative of motion with respect to time, velocity, and/or position.
The instantaneous speed is the rate of motion at any given time.
